For me it is amazing to learn Phonology, because generally when you learn English not much programs teach you this subject and I feel advantaged learning it, now I know the correct way to pronounce vowels and consonants, talking about consonants I can say that they are very simple to recognize and pronounce.But talking about vowel sound some of them are still difficult to recognize because the spelling are different from the sounds. And I really need more practice in that.
